is it a way to reset the main quest and side quest storyline so i can do them all over again
without starting from the very beginning?
Yes, Start Menu, New Game.
Using the console to reset all the quest stages is not going to be fun. Not only do you have to reset the Journal Updates, you will have to reset all the scripts, all the things that happen in the game due to the scripts, your character progression regarding shouts, reset all the Dragon Lairs, Word Walls, Dragon Priests, Unclear all the dungeons involved, put the bosses for those back, reset all the civil war battles and outcomes, move all the Jarls and or Imperials back to their starting places, reset their scripts etc etc etc.
Really, just roll a new character, it would be more fun. And, take less time.
